From Wikipedia, the free encyclopedia: Rovinj (Croatian: [rǒʋiːɲ]; Italian: Rovigno; Istriot: Ruvèigno or Ruveîgno; Ancient Greek: Ρυγίνιον, romanized: Rygínion; Latin: Ruginium) is a city in Croatia situated on the north Adriatic Sea with a population of 14,294 (2011). Located on the western coast of the Istrian peninsula, it is a popular tourist resort and an active fishing port. Istriot, a Romance language once widely spoken in this part of Istria, is still spoken by some of the residents. The town is officially bilingual, Croatian and Italian, hence both town names are official and equal.
